我们做插入句题按照下面三个步骤完成：
第一，把需要插入的句子找到“具体含义概念”。
第二，看需要插入句子的意思是适合在原文需要插入的大概哪个部分，是开始，中间，还是结尾。
第三，在最可能的开始，中间或者结尾再比较具体信息。具体含义名词最好一致，意思与逻辑也正好吻合。
我们以Extinction of the Dinosaurs的第五段为例。
Ir has not been common at Earth’s since the very beginning of the planet’s history. Because it usually exists in a metallic state, it was preferentially incorporated in Earth’s core as the planet cooled and consolidated. Ir is found in high concentrations in some meteorites, in which the solar system’s original chemical composition is preserved. Even today, microscopic meteorites continually bombard Earth, falling on both land and sea. By measuring how many of these meteorites fall to Earth over a given period of time, scientists can estimate how long it might have taken to deposit the observed amount of Ir in the boundary clay. ·These calculations suggest that a period of about one million years would have been required. ·However, other reliable evidence suggests that the deposition of the boundary clay could not have taken one million years. ·So the unusually high concentration of Ir seems to require a special explanation. ·
13. Look at the four squares [·] that indicate where the following sentence could be added to the passage.
Consequently, the idea that the Ir in the boundary clay came from microscopic meteorites cannot be accepted.
Where would the sentence best fit?
第一、先看需要被插入的句子，前面的Ir肯定是文章主旨，这里的具体信息应该是came from microscopic meteorites，是负态度。而且副词Consequently很重要。
像这篇文章需要插入意群不是整个段落，那么就需要看下前面第一二句的意思。
Ir has not been common at Earth’s since the very beginning of the planet’s history. Because it usually exists in a metallic state, it was preferentially incorporated in Earth’s core as the planet cooled and consolidated. 是说Ir在地球上不常见。这和来自彗星有共同之处。
第二，读一下需要插入意群的关键词，找到最可能的大致位置，是开始，中间还是结尾。
